Moving from 4.0.6 to 4.1b2 I was not happy when I started switching one app as many things didn't work out of the box. But ... as I could identify and remove one hurdle after the other ... a pretty much faster app reveals ... I am starting to like 4.1 ... and so will the endusers if I succeed in removing the remaining hurdles ... thumbs up on 4.1 :-)
